Digital signage is a powerful tool for sharing information in high-traffic areas — but if it’s not designed with accessibility in mind, important messages may be missed by members of your audience. Following accessibility best practices ensures that everyone, including people with disabilities, can access and understand your content.
Prioritize Readability:
- Ensure Sufficient Color Contrast
- Choose text and background colors that meet WCAG 2.1 Level AA contrast ratios (at least 3:1 for large text).
- Avoid placing text over busy images.
- Use solid backgrounds behind text whenever possible.
- Select Readable Fonts and Sizes
- Use simple, sans-serif fonts (e.g., Arial, Calibri, Verdana).
- Avoid decorative or script fonts for main content.
- Keep text large enough to be read from a reasonable distance (minimum 24–30 pt for close viewing, larger for long distances).
- Keep Text Concise and Clear
- Limit the amount of text per screen so it can be read in 10–15 seconds.
- Use plain language and avoid jargon.
- Break up information into short, scannable segments.
- Ensure Adequate Display Time and Transitions
- Allow enough time for viewers to read the content before transitioning to the next slide.
- Avoid rapid flashing or blinking content, as it can trigger seizures in individuals with photosensitive epilepsy.
Provide Multiple Formats for Critical Information:
- Share important messages on other accessible channels (e.g., website, email, printed flyers).
- Include QR codes or short URLs so users can access information with their own assistive technology.
Make Multimedia Accessible:
- Provide captions for videos shown on digital signage.
- Offer audio descriptions for important visual information when sound is available.
- Avoid autoplaying audio in public spaces unless essential.
Consider Sign Placement and Viewing Angles:
- Mount screens at a height and angle that allows comfortable viewing for people using wheelchairs or of shorter stature.
- Avoid glare from sunlight or overhead lights.
